Noctua NF-P14s redux-900, Ultra Quiet Silent Fan, 3-Pin, 900 RPM (140mm, Grey)

This was part of a new computer build I did a few months ago. So far, it has worked flawlessly silently. Excellent fan.

I had to replace a fan inside my PC, and while I was there added two of these to the top of the case to exhaust air. They are nearly silent and move a decent amount of air. I found Noctua makes quality fans and have used them in various projects.

Bought these with some NF-S12B's to put in a new system for the living room in a Noctis 450. I've been a faithful Noctua fan for a many builds and have always gotten great performance out of their products. However, the main product line's color scheme has always bothered me. I also have a machine full of the Industrial PPC line, which do a phenomenal job at cooling and look great in black; but sound like a jet taking off.I wanted something quiet and high-performant that matched the black and silver theme of this build, as it has a Rampage IV Black from my workstation, which I was upgrading, and Corsair Dominator RAM. I was pleased to discover this product line from Noctua, which promised significantly lower noise profiles than other 'silent' fans. After installing these, I was really impressed with how quiet they were. Then, having an Asus motherboard, I ran the Fan Expert tuning system and then set it to the Silent profile. Between the fans and the software, you literally can't tell the computer is on now if I've say, switched source on the TV to another device like our PS3. The Noctis has a red light that it casts on the floor, and we have to use that to verify the machine is on if it's asleep or the source is switched. The machine is that quiet.We installed a Vive on this machine, and the noise from the base stations, which isn't very loud... is * louder than the computer *. The PS3, which used to be the quietest device in the room, and is indeed fairly quiet, especially compared to, say, the XBox 360, now sounds like a feight train by comparison. Even at full voltage, as other reviewers have said, these fans will still be quieter than any other fan on the market.I've run Prime95 with Real Temp GT and the fans got just barely louder under load, while CPU temps remained relatively frosty thanks to the H100i I have installed.So...Pros:- At ~$15, much cheaper than many silent fans, some of which cost $30 nowadays, and cheaper than most other Noctua fans- Truly silent operation- Noctua build quality- A cool color scheme that, being gray, truly will match any systemCons:Truly, noneDo note that this fan is just that, a fan. It comes with screws, but none of the dampeners, voltage regulating cables or extension cables most Noctua fans come with. Personally, I prefer that, as that stuff (other than the dampeners) usually ends up in a junk box somewhere. I installed these with a set of compatible Noctua dampeners, the NA-SAV2's, in red. (Note that this fan is not compatible with the corner-style NA-SAVP1 dampeners).If you want a truly silent fan that will last forever, get this fan. You will * not * be disappointed. This review applies to the NF-S12B as well.

If your looking at this you probably know what you need, you're here

perfect for what i needed

This fan was the quietest that I could find. Being used to exhaust warm air out of a audiophile cabnet, hence the 900 rpm and low decibel requirement. 2 of them move quite a bit of air as expected being 140mm also like the 150000hr mtbf should last along time. I use a 12v temp adjustable controller with these. So far so good.

Have had two of them running in my Phaenteks AT case, really appreciate the quietness. A couple of things to note, the power cable (3 pin) is not super long. If you have a long run from the fan mounting location to the power pins, you may find the cable a little short. If like me, you have plenty of 3 or 4 pin jumpers on your main board it won't be a problem. Some people are very particular about hiding cables and such, so fair warning. If that's you, make sure you have adapters to extend the length. The other thing, the screws included in the box are great for some cases but not all. I needed to buy some #6-32 machine screws to get the mount how I wanted it. No big deal, for the extra 2 bucks I had to spend at Home Depot. All said and done, I would gladly buy again. Would give 5 stars for a little longer power cable and better assortment of long screws. :)

I purchased these to replace the 120mm Arctic and Corsair fans in my NZXT H510 case. These are only a few dollars more, and are SIGNIFICANTLY quieter, especially at full load. They have just about the same rated CFM, too. I don't have an overclocked "enthusiast" machine, but it's no slouch (Ryzen X series and GTX1080), and I run 4K games and demanding apps regularly. I found my temps to be just as good--if not better--with three of these and a single 120mm version, and the PC is so, so much quieter. Part of that is also the Noctua CPU cooler I got, but the fans definitely contribute. One thing I'd say is to get the rubber corner pieces as well--I had to selectively tighten/loosen certain screws to avoid some minor fan contact and noise, which I am going to solve by just adding the corner bumpers. These are great value, in an attractive colorway.
